In winter, the average farmer household has unfinished pesticides at home, and if it is not properly kept, there will often be problems such as deterioration or explosion. There are three kinds of pesticides, namely solid, liquid and gas, which are different from the external forms. Different types of pesticides have different requirements when they are stored.
Liquid pesticides should focus on thermal insulation and sun protection, avoid high temperatures to prevent contact with the air; to stay away from fire, to prevent contact with oxidants and alkaline substances, generally should be placed in a ventilated place away from Japan, a cool dry place, generally pay attention to when the bottle is stored up, Do not stand upside down, do not store strong oxidants such as nitrates and strong acids, and organic materials such as charcoal and paper scraps. Bottle caps and stoppers for bottled pesticides must be tightly capped to prevent decomposition. Some pesticides have their own characteristics. For example, phoxim and trifluralin are easily decomposed when exposed to heat, and should be stored in a dark and cool place. Dichlorvos are easily decomposed and volatile, so they should be sealed and not stored for a long time. Organophosphorus pesticides are mostly susceptible to alkali decomposition and failure, and should not be mixed with alkaline substances when stored. Bottled liquid pesticides are susceptible to freezing at sub-zero temperatures, forming lumps or cracking the bottles. Therefore, it is best to use rice husks, etc. for thermal insulation during storage.
Solid pesticides should mainly pay attention to moisture and moisture. Therefore, it should be made of wood, cement or sun-dried husk or wheat straw, straw, etc., and pay attention to ventilation and tide. The aerosol should not be stored together with volatile, flammable or explosive materials. The temperature should not exceed 30°C.
Gas pesticides are not commonly used as such pesticides, and methyl bromide is commonly used. When storing in winter, the same should be prevented from high temperature, and to avoid severe collision, often check the valve for looseness, there is no gap in the cylinder to prevent explosion.
Microbial pesticides should be kept in a low-temperature and dry environment, and they should be protected against high temperature and humidity. The storage time should not exceed 2 years.
